@kazrael2119
You suggested to add directive as a fix to this issue. Seems the new run still doesn't work.

In addition, could you also document this at the [trouble-shooting FAQ wiki](https://github.com/Azure/azure-rest-api-specs/wiki/SDK-Validation#net-sdk-generation-error-fix-guidance) so that the future user requests can be directed to this page?
